 Many older adults claim time speeds up as they get older, which can be explained by forward telescoping.Since forward telescoping leads people to underestimate the amount of time that has occurred since an event, people may feel as if time has passed quickly when they discover the true amount of time since that event.This explanation is one reason for why people perceive time as moving faster as they age, but it does not take into account changes in the amount of telescoping that occurs with age.
